This is the 3D model of a temperature sensor circuit using an op- amp and LM35 sensor . Circuit to check temperature of any where you needed. you can render this or you can 3D print this circuit. It may be helpfull to you to make model of a circuit or to demonstrate the use of an op - amp or temperature sensor.

This project uses IC LM35 as a sensor for detecting accurate centigrade temperature. Linearity defines how well over a range of temperature a sensor’s output consistently changes. Unlike thermistor, Linearity of a precision IC Sensors are very good of 0.5°C accuracy and has wide temperature range. its output voltage is linearly proportional to the Celsius (Centigrade) temperature.

The LM35 is rated to operate over a -55° to +150°C temperature range.It draws only 60 µA from its supply, it has very low self-heating, less than 0.1°C in still air. LM35 Operates from 4 to 30 volts.
